WOOD-ORNAMENTING MACHINE.

Specification of Letters Patent.

Patented Jan. 22, 1907.

Application filed- December 7, 1905- Serial No. 290 844.

To all whom it may concern.-

Be it known that I, ELMER C. DITTMAR, a citizen of the United States, residing at VVilliamsport, in the county of Lycoming, State of Pennsylvania, have invented certain new and useful Improvements in VVood-Ornamenting Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to an apparatus for ornamenting wood, and particularly to a con-- struction adapted to ornament simultaneously all the different surfaces of an article by compression thereof toward the radial center of the article.

The invention has for an object to provide a plurality of movable dies adapted to approach and compress the entire periphery of the article both radially and tangentially to the center of the work and. produce a resultant radial pressure toward its center, and thereby prevent splitting of the material of the article at the sides thereof and permitting an impression of the dies of equal depth upon all of its periphery.

A further object of the invention is to provide an improved construction and arrangement of work-holders adapted to travel with the diesconstructed and arranged to support the work in proper position when the several dies of the series engage the same.

Another object of the invention is to provide means for mounting these dies whereby one of the dies is held stationary and the opposite die approaches the same, while the dies at each side travel at a less speed in their movement toward the stationary die and each other.

Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.

In the drawings, Figure 1 is a side elevation of the invention. Fig. 2 is an end view thereof with intermediate parts broken away. Fig. 3 is a detail perspective of the workholder. Fig. 4 is a detail section on line 4 4, Fig. 1. Fig. 5 is a detail perspective of one of the dies and means for mounting the same, and Fig. 6 is an elevation of a portion of the completed article.

Llke numerals of reference indicate like parts throughout the several views of the drawings.

This invention contemplates the use of a plurality of dies adapted to approach each other and an article to'be ornamented, so as to impress the entire surface of the article, and any desired construction or arrangement of such dies may be used. For the purpose of illustration one form thereof is herein shown and comprises the die 1, stationarily held, while the opposite dies 2 move toward the-same, and the side dies 3 and 4, being interposed between the movable and stationary dies, receive a resultant oblique travel from the position shown in full lines in Fig. 1 to that indicated by dotted lines therein. The die 1 is mounted upon a fixed frame 5, and the die 2 is mounted upon ainovable frame 6. Each of the die-holders 11 is secured in position by means of undercut grooves 7 from which bolts 8 extend, said bolts being adapted to pass through a laterally-extended slot 9' in the flange 10 of the dieholder 11, by which means the die may be adjusted both longitudinally in the slot and laterally thereof by means of the bolt 8. The holder 1 1 is preferably formed with a heatingchamber 12, into which any desired heating means may be introduced, and is provided with a segmental or curved face 13, adapted to receive the die, which is of similar shape and is provided with laterally-extending ribs 141, by means of which it is secured to the holder, as shown in Fig. 5. The ribs 14 are located near the edge of the die, so as to permit complete contact between the edges 15 of the dies when in operative position, as shown by dotted lines in Fig. 1.

The side dies 3 and 1 are each mounted upon a triangular carriage 16 in the same manner as the dies 1 and 2, so as to permit similar adjustment thereof. The triangular carriages 16 are interposed between the diagonal faces 17 at each side of the frames 5 and 6, so as to produce a resultant oblique movement of these carriages when the frame members are brought together, as indicated by arrows, upon said carriages, the movement of said carriages upward being at a less speed than that of the lower frame 6 in order to secure a proper and simultaneous engagement of all of the dies with the article to be ornamented. The carriages may be mounted upon the frames in any desired manner for instance, by means of a gib 18, secured to the carriage by bolts 19 and having a rest in open sockets 25, carried by the carriages 16, hereinbefore described. This permits the necessary travel of the carriages longitudinally of the arms during the lifting movement thereof without producing any lateral, travel of the arms. This lateral travel is effectually prevented by means of a depending rod 26, passing through a sleeve 27. secured to the movable frame 6, so as tov travel therewith and also upon the rod 26.

The work-rest 28 may be of any desired configuration-for instance, V-shaped, as shown in Fig. 3-and provided with support ing-standards 29, adjustably mounted in sockets 30, carried by a sleeve 31, which is also adjustably mounted upon the lower portion 32 of the work-holder by any suitable meansfor instance, a set-screw 33. As shown in Fig. 2, these work-holders are duplicated at opposite ends of the machine.

In the operation of the invention the parts are at rest, as shown by full lines 111 Fig. 1, when the material to be ornamented is placed upon the work-holder and the lower die moved upward toward the fixed die. The result 'of this motion transmitted through the frame of the lower die is to cause an inward and upward travel of the carriages carrying the side dies, producing a re sultant diagonal movement. The upward movement of the side dies is approximately I one-half as rapid as that of the lower die, and

the work-holder being mounted for vertical movement with the side dies thus carries the work into proper position beneath the fixed die, while the side dies travel on the workholder, thus producing a centering device which moves the work to be ornamented in a vertical direction and permits the same to be readily placed in position and removed, while it presents the work in such a position that the dies simultaneously engage the material to produce a resultant radial compression thereof. It will be observed that although there is a difference of speed of the movement of the dies toward the center, yet they meet and engage the work simultaneously.

The construction of the work-holder is such as to permit its ready replacement and removal from the carriages upon which it is supported, while the rest is capable of both vertical and lateral adjustment to be properly centered. The die-holders are also adjustable laterally and longitudinally, as it is essential that they be in accurate position in order to secure a simultaneous action between the parts.

Having now described my invention and set forth its merits, what Iclaim, and desire to secure by Letters Patent, is

1. A device for ornamenting wood. comprising an expansible and contractible series of ornamenting-dies completely inclosing the periphery of the work when contracted and all acting mutually to sustain the pressure of each other, the movable dies all moving toward a common center, and means for equalizing this movement.
